handle multiline text. (add_face_info): add some extra information found
2002-12-09 James Henstridge <james@daa.com.au>
* src/font-view.c (add_row): handle multiline text.
(add_face_info): add some extra information found in SFNT or Type1
fonts.
(create_text_pixmap): change the font output.
2002-12-06 James Henstridge <james@daa.com.au>
* src/ftstream-vfs.c (FT_New_Face_From_URI): if the URI looks
local, bypass gnome-vfs to open the face (small optimisation).
* src/font-view.c (create_text_pixmap): only display the font at
its fixed sizes if it is not scalable. Before we were ignoring
the outlines on fonts such as Lucida Console, which includes both
outlines and bitmaps for small sizes.
